Be it know-n. tha-tI, PLINY Carocci, a citizen of therPnitedStates, residing 1n the of NewlJersey, have invented certain` `new A and useful Improvements in Plionograph the stylus point will groove, and not upon i. i' the details holder ,of a universal ymovement of thestylus point l i as it follows such groove: that .45- parts disclosed' insaid' Sound-Boxes; andfI declare the following tok be a full, clear, and exact description of the same, such as will enable others skilled in the art to'make, construct, and use the same.

vMy invention relates 'tothat class of sound boxes whereinY the reproducing stylus is caused to follow a. helical groove in a cylindrical phonograph record, and-its particular purpose. is to so construct the stylus, and its connected parts asto permit is to say, i

at any portion of the record groove, itshould deviate from a true helix as 1s often the case, bear directly into the sulting in a more perfect reproduction of the selection upon .the record.

cation of -the structure of the parts and` a consequent reduction' in the costof manujA preserving all of' facture, at thesame time,

the requisites of a perfect sound boX.

Another object accomplished by my im-v rovement is the simplifying of themeans ihr throwing the `recording or .reproducing stylus out of action 35' during the replacing of' a blank or record. 4

In another `application, I Ih avewsetiforth of the construction vo-f-the' sound box proper, and of thestylus Iholder and its connection with (the diaphragm, and they need not be repeated here but the followf' ".ingdescription` will beconfined tothe de?.`

tails 'ofthe universal` connections and shifting devices, with only"such reference to the other `apl'olicatio'n ,asn 'ay be' necessary to a full .understanding of -lrllie present improvement. The said application bears Ser.l No. 613,813 led Mar.` 11, 1911. 'i

perspective bending `substantial respects like those described in my application -above yreferred to.

` Upon the rearside of the box 1, is rigidly secured, the bracket 4, with its upper end slotted as at 5, and having the' upwardly flanged bearing lugs 6 `and 7 The two legs 8 and9, are for the purpose of affording a broad base 'by which the bracket `is secured to the box l, by means of the screws or rivets 10.' The flanged bearing lugs Gand 7, are formed by bending the `metal of whichthe bracket is made,

and l2, and the shiftingdevice apertures 13 `and 14, the latter being somewhat larger than the aperture 13.` The head `of the bracket, .that is, lugs 6 and 7is bent at right angles to the the bracket, so as to overhang and project forward ofrthe box 1, as shown in Figs. 1 and 2. i

Mounted within the channel formed by the lugs y6 and 7, upon a pivot pin 15, which is inserted through the apertures 11 and 12, is the two-armed stylus lever 16, one larm 17, lying horizontally in the' `channel and the `other `arm 18, `extending vertically through the slot 5, down in front of the diaphragm shifting device such as 'l Fig. '8 is diaphragm 3, `and its the part having the bearing i Fig. 9 is an edge view Y at right angles to its plane, providing the pivot bearing apertures 11 3, the slot 5, acting as a guide 4to confine the movements of the armlS, within 'a vertical plane atright Vangles to the plane of the diaphragm. The stylus-lever thus formed middle to form the two ri'ght angled arms 17V and 18 with the pivot pin 15 located at their angle. The horizontal arm 17, is provided with a weight 19,'wl1ose tendency is to '1s 1n fact a lever bentsubstantially at `its tilt .the lower end of the arm 18, forward, p

or 4away :from the diaphragm 3. In some cases I may `supplement the weight with a spring 20, the yupper end of which. is connectedto the arm 17 ,and its lower endvto a-l v laterally projecting lug. 21, upon the bracket '4, as shown. Or if desired, II may dispense" with the weight 19,`and use the spring alone,.

according' to the class of'record being reproduced. Iy wish it to bev understood that I do not coniine myself to the weight alone or the spring alone, -as in somecases onewillV operate to give a better reproduction, while in others,d to get the'best results both weight and spring must be used.'

At the lower endy ofthe arm 18,* is an aperture into which is swiveled the eye-pin 22, in the slotted outer end of which is pivoted the stylus holder 2, as shown, the construction being such that the point of thel stylus, may sway froii'i".side to side upon the eye-pn122, as it follows the record, groove, and yet not interfere with its following thel excavations and elevations in the bottom-of thegroove. v l Y. x

As a means for shiftingthe stylus oint I into andout of contact with'a record, may

`use the shifting pin 2 3, which is located in the apertures 13 `and 14,:as shown; 4This pin has two diameters, upon eitherof which the.

'arm `17, may rest.. The two diameters are connected with a slightfcone so that the slid'- -of the pin endwise under the arm 17,

in u wi `either raise or lower the armAV 17, and

consequently' move the arm; 18 towardor. away from the diaphragm, as the .arm 17,

rides upon the large or the small diameter of the pin23.' The handle 24,'.integral with the 23projects outsidethe lug 7, whereby the pin inlay-be readily manipulated, the

' other `end Abeing headed'to prevent detachmodication of the shifting device.` In t ment. j

..case`, I 'use a-"cylindrical pin 25, witha knurledheadfor turning the same. Aportiongof` this pm is. .cut' away or halved,

,shifted- `'av'vay from the diaphragm f "the1 "stylus .pointupon the recor 4 the in 25, is rotated to brin' the cylindrical,
